VHG is right - sp3 is at RC2 and other TLAs
(three letter abbreviations!!!!)
Its not illegal ... but not wise ....
If there is an uninstall option ... use it .... the point of RCx is that idiots like me run it on a machine that doesn't matter ....to try and break it.
at RC2 it's usually almost ready ... but until it's released there could be a last minute change due to something serious .... and you don't want to be the one to find it (even then .... there will be changes).

The best way to do it is to slipstream SP2 into your old CD (under some conditions windows won't accept the old one as genuine)
however .... to answer your question .... it takes bl**dy ages.
especially if you use the "punters" version which is quite a small initial download .... all it is is a downloader ... so when you run it ... it goes off and does the download (which takes 30-50 mins)
it then start the install ... puts all the files into a temp folder ..... then it examines your system to see which options need updating .... doing this takes a fair bit of processing ... but with a decent amount of memory - very little disc space .... so from your point of view is just sits there looking dumb. for 20 mins or so
(easiest way to see it "finkin'" is ctr+alt+del and look at the performance .... you'll see the processor processing.
I can't remember just how long (I slipstreamed ages ago) but you are talking serious time.
if you bail out ... it needs to undo everything it's already done .....
if you switch off ... there is a chance that it won't be able to ... and you'll get problems.
